Kemurikusa

A world covered in a red fog. Inside a decaying building, Rin, a girl with an updo, and Rina, a girl with pigtails, search for water. Just when they were about to report to Ritsu located far away, crisis strikes.

Thanks to Wakaba's quick thinking, Rin, Ritsu, and the Rinas are saved. Wakaba's identity is still unknown, but Rin has him tag along for a little expedition.

The party is on the move in search of water. The new scenery and objects pique the interest of the ever-curious Wakaba, forcing the Rinas to explain everything. During their journey, they witness something...

Wakaba shows a tremendous interest in Kemurikusa. He learns that there are many different kinds in this world, such as the Kemurikusa he received from Ritsu. The group now heads to Sky Bridge.

The party continues their search for water. They are forced to walk on foot at one point and decide to give water to Midori. But then...

The sisters sleep in the train car in order to rest up. Wakaba goes out alone in search of Kemurikusa, but finds himself lost after getting too caught up in his expedition. Deep inside the building, he sees something unexpected.
